My WooCommerce store periodically spikes its CPU and RAM until both the site and the entire VPS become unresponsive. From what I can see, the culprit is most likely a plugin or theme conflict rather than a sudden traffic surge. I haven’t installed or updated anything recently, and I already run a performance-optimization plugin, yet the problem persists. Here’s what I need: • a clear diagnosis of what is eating the resources (slow queries, rogue cron jobs, misbehaving extensions, theme code, etc.) • permanent fixes or configuration changes so the site stays stable under normal load • a concise report explaining the root cause and the steps you took I’ll provide full SSH / cPanel (or Plesk) access to both the server and the WordPress files, plus staging if you prefer to work there first. Once you’re done, I expect the store to load normally, pass a quick stress test without crashing the VPS, and leave me with practical guidelines to avoid the issue in the future.
